The invention briefly described consists of a lubricating device adaptedto conduct oil from the oil sump in the journal box to the journal orcar axle. The device is preferably mounted on the end of the axle andcomprises a bracket supported on the axle and having mounted thereon agear adapted to dip into the lubricant in the sump and driven by a gearfixed through the axle. Means is provided for conducting the lubricantwhich is squeezed out of the intermeshing gear teeth to the surface ofthe axle, so that the interengaging parts of the shoe mounted on theaxle and the reduced end or journal 0 formed on the axle will belubricated by a continuous stream or film of lubricant or oil.

The invention furthermore utilizes means for insuring an initiallubrication of the bearing or journal before the gear pump or lubricantsup- 5 plying means starts to function.

Further details of the invention will appear from the followingdescription. 1

In the form of the invention shown in the drawings, there is illustrateda car axle or shaft 10, having a reduced end or journal 11 formedthereon. A flange or collar 12 is formed on the endof the journal 11.

The axle extends into a journal box 13 of the usual construction, havinga well or sump 14 in the bottom thereof. One end of the journal box isprovided with a U-shaped channel 15 in which are positioned closuremembers 16 and 17. A collar or flanged ring 18 is mounted on the shaft10 and has annular spacedwebs 19 and the upper and lower members 16 and17 have semi-circular Webs 2D and 21 disposed between or interspacedwith the webs 19 and surrounding the upper and lower halves of theshaft. The staggered webs 19 and 20, 21 confine and prevent escape ofthe lubricant.

The lower section 17 has bars 22 extending upwardly through channels oropenings .in the upper section 16 and provided with openings 23 arrangedto receive the outer ends of slidable 5 latches 24 which are releasablyheld in their latching positions by a spring 25. When the upper sectionis to be raised the ends of the spring are raised and the latches 24 aredrawn toward each other, thus releasing them from the bars 22, whereuponthe upper section 16 can be raised.

The journal box has an opening 26 at the opposite end thereof which isnormally closed by a spring pressed cover 27 of the usual construction.

In the form of the invention illustrated in Figs. 1 to 8 inclusive ascrew or stud 30 is secured to and extends beyond the journal 11. Thestud has a head or enlarged portion 31 atthe outer end thereof and anintermediate portion 32 between the head and the journal flange orcollar 12. A gear 33 is mounted on portion 32 and has a hub 34 and astud 35 projecting from the hub and extending into the collar 12. Aplate 36 is positioned on the hub 34'betwee'n the gear 33 and thecollar. A casing 37 is mounted on the head portion 31 of the screw 30and encloses the gear 33 and a gear 38 which meshes therewith, betweenthe casing and the plate 36. The gear 38 is mounted on a stud 39 whichin turn is carried by the casing and plate;

The casing and plate are cut away or recessed, as shown at 40, at thelower ends thereof to permit the lubricant in the sump 14 to enter theteeth of the gear 38 and to be carried upwardly in a manner hereinafterdescribed. The casing 3'7 hasformed thereon laterally extending wings 41and 42 which extend across the lateral edge portions of the gear 39, asshown in Fig. 8, and communicate with a crescent shaped trough 43carried by the plate 36. The trough 43 extends beneath'the collar orflange 12, as shown particularly in Figs. 1, 3 and 5, and may haveformed therein grooves 44 for receiving the lubricant.

A bearing shoe 45 is mounted upon and rests on the upper portion of thejournal 11 and is provided with a lug 46 at the outer end thereof whichextends over the upper portion or top of the flange or collar 12. A pin47 projects be-. yond the lug 46 and is. disposed between upwardlyextending lugs 48 and 49 which are formed on the upper ends of thecasing 37 and plate 36 respectively. The engagement of the lugs with thepin prevents any tendency of the casing and plate to rotate with thejournal.

The shoe 45 has an upwardly extending flange 50 at the opposed endthereof and is provided with longitudinally extending ledges 51 and 52along the lateral edges of the shoe. The ledges are preferably grooved,as shown at 53 and 54, and these grooves communicate with upwardlyinclined end grooves 55 and 56. The ends of the grooves 55 and 56 areopen and are disposed adjacent the lug 46..

The bearing shoe 45 is mounted in position on the journal by means of amember 60 which rests on the shoe and has inclined end surfaces 61 and62 which rest on the upper surface of the shoe. The shoe 45 is providedwith laterally projecting lugs 65 and 66 on which are pivoted members orplates 67 and 68. The plates 67 and 68 have mounted on the lower endsthereof pockets 69 within which are housed longitudinally extendingwipers 70 of absorbent material, such as felt. The wipers 70 engage thejournal substantially throughout the length thereof.

The plates 67 and 68 are provided with extensions which are disposedoutside and closely adjacent to the opposite peripheral portions of theflange or collar 12, as shown in Fig. 5. A fin or web 71 .formedon theplates 67 and 68 rests lightly against the collar and is adapted tointercept and deflect lubricant which is being carried upwardly by thecollar, the lubricant passing through a passage 72 between the fins orwebs 71 and a parallel fin 73 into a trough extension 74 whichcommunicates with a trough 75 carried by the pivoted plates 67 and 68.The trough 75 has perforations or openings 76 and '77 which permit thelubricant to escape therefrom and to engage the felt wipers 70.

The lubricating device above described operates as follows: When thejournal 11 rotates the gear 33 will also be rotated, thus causing theintermeshing gear 38 to rotate. The lubricant in the sump 14 will bepicked up by the teeth of the gear 38 and will be squeezed out betweenthe teeth of the gears 38 and 33 and be conducted by the deflectingwings 41 and 42 to the crescent shaped ledge or trough 43. From thetrough it will be carried upwardly by the collar 12 and will beintercepted by one or the other of the fins or webs 71, depending on thedirection of rotation of the collar. The lubri cant will then pass intothe trough extension 74 and thence into the trough 75 from which it willdrain to the wiper 70 carried by the trough and plate 67 or 63.Particular attention is called to the fact that thewipers will be at alltimes saturated with lubricant and will furnish lubricant to the shaftwhen it is started and before the lubricant supplying and distributingmechanism is operative.

Any lubricant that is carried upwardly by the collar beyond thedeflecting fins or webs 71 will be intercepted by the lug 46 and will beconducted along the bearing shoe 45 through the grooves 55 and 56 andinto grooves 51 and 52. Escape of the lubricant along the shaft 10 isminimized by the ribbed ring or flanged collar 18 and the correspondingribs carried by the closure members 16 and 17.

Thus, a continuous stream or film of oil will be fed to the journalwhenever the axle is rotating. It will be understood that when the axlerotates in one direction the lubricant will be deflected by the wing orweb 41 to the crescent shaped ledge and when the axle is 1'0- tated inthe opposite direction, the same function will be performed by the wingor web 42. A portion of the lubricant squeezed out of the intermeshingportions of the gears will lubricate the boss 30.

In the form of the invention illustrated in Figs. 9 and 10, thelubricant is conducted from the sump to the interengaging surfaces ofthe shoe and the journal in a similar manner. In

Figs. 9 and 10 a gear 80, similar to the gear 33 is fixed to the journal11 and meshes with a gear 81 carried by a stub shaft 82, which in turnis carried by a bracket 83. The bracket 83 is pivotally mounted on aboss 84 formed on the gear 80.

A sleeve 88 is connected to the gear 81 and is mounted on the stub shaft82 and a roller 89 is secured to one end of the sleeve. The sleeve androller are held on the stub shaft by a head 90 on the end of the shaft82. The sleeve 38 has radial openings 91 to permit the passage oflubricant through the sleeve to the stub shaft. The hub of the bracket83 which is pivoted on the boss 84 is also provided with openings 93 forthe purpose of permitting the lubricant to gain access to the boss 84.

In the form of the invention shown in Figs. 9 and 10, the bracket 83 isheld against rotation by the bifurcated end 95 of a bolt 96 whichengages a laterally. projecting web 9''! formed on the bracket. Theouterend of the bolt 96 serves as a securing means for the cover plate98 of the journal box.

The bracket 83 has formed on its upper end above the boss 84, a curvedweb 100 and a vertical web or fln 101. Ihe web 100'and fin 101 serve todeflect oil or lubricant carried upwardly by the gear and as thelubricant flows over the hub of the bracket, it will enter the openings93 and lubricate the pivotal mounting of the bracket on the boss 84.

It will be obvious that as the journal 11 in Fig. 9 is rotated, theroller will carry a film of oil from the sump 14 to the under surface ofthe journal. The oil or lubricant will then be carried around the axisof rotation of the journal to the coacting or interengaging surfaces ofthe shoe and journal. Furthermore, the lubricant will reach the coactingsurfaces of the sleeve 88 and stub shaft 82 and the interengagingsurfaces of the hub of the bracket and the boss 84.

In the form of the invention illustrated in Figs. 11, 12 and 13, thereis shown a bracket which is mounted on a boss 30 similar to the bossshown in Fig. 1. The bracket 110 has an upwardly extending portion 111having a slot 112 which receives a pin 113 secured to and extendingbeyond the end of the shoe 55.

The bracket 110 has a stub shaft 140 secured to the lower end thereof,on which is mounted a gear 142 which meshes with the gear 130 secured tothe end of the shaft.

The bracket 110 has also formed thereon or secured thereto, laterallyextending diverging wings 115 and 116 which extend longitudinally of thejournal and outside the periphery of the journal flange 12. The wings115 and 116 form troughs and are provided with upwardly extending webs118 for intercepting the lubricant carried around by the flange andcausing the lubricant to be conducted along the shaft through thetroughs formed by the wings and into a pan 12f) connecting with thetroughs and disposed beneath the journal 11. The portion of the panbeneath the journal has vanes 121, 122 and 123 for directing thelubricant longitudinally of the shaft or journal.

In the form of the invention just described, the lubricant is carriedupwardly from the sump by the teeth of the gear 142 and is squeezed outof the teeth as the teeth of the gear 142 mesh with the teeth of thegear 130. The lubricant which is squeezed out is caught in the troughsand is intercepted by the webs 118 and is conducted beneath the shaft bythe troughs and the pan 120. The shaft journal 11 then picks up thelubricant.

From the foregoing description it will be clear that simple, practicaland cfficient mechanism has been designed for use with bearings and thatlubricating means such as that described will effectively feed lubricantto the interengaging surfaces of the bearing at all times during therotation of the shaft or journal.

Although certain specific embodiments of the invention have beenparticularly shown and described, it will be understood that theinvention is capable of modification and that changes in theconstruction and in the arrangement of the various cooperating parts maybe made without departing from the spirit or scope of the invention, asexpressed in the following claims.
